Guild Wars 2

I filed an in game bug report on this one, but I was hoping to get a response from someone at Anet on this one for some clarification.

I logged in today, and happened to catch the tail end of a Teq event (this was before the silliness with client crashing code started). The Teq event failed, but when it failed I got not one, but two daily achievement chests, for a total of 2 mystic coins, two drips of karma, and two green luck essence items plus a mystic stone.

Is this a known issue, and if so, what are users supposed to do about it? I don’t want to assume that we should just keep the loot and game-on, because Arenanet has an overkill policy for exploits. Bottom line, I do not want to get banned because I deposited a mystic coin, or used a luck essence.

So what do the users do in this case?

they caused double daylys and monthlys about 10 times now play on its fine
